The Noiseblocker NB-Multiframe M12-P 120mm x 25mm Ultra Silent PWM Fan
is part of the family of Germany's quietest fans. The PWM technology
gives your motherboard or fan controller more control over the fan's
performance than traditional fans. The new Multiframe® technology uses
silicone rubber corners to mount the fan, making it as quiet as
possible. The NB-NanoSLI® bearing is also vital in providing the fan
with its near silent performance and long lifespan that earns it a 6
Year warranty. Noiseblocker fans are the new standard in the industry
of quiet computing!

Features:

NB-Mulitframe® Technology
The high tech multipart chassis has integrated vibration
absorbers at each corner, making the fan supported directly by rubber.
Even the fan's main framework uses anti-vibration glass-fiber
reinforcement.
